While it’s not exactly a surprise that a college teammate would vouch for his quarterback in a public setting, what Brown and Quessenberry had to say about Mayfield and Rosen is somewhat telling. Each said their teammate isn’t what he’s portrayed to be.

Rosen’s case is interesting. As a passer he is rarely criticized. Everyone seems to be in agreement that he’s more mechanically sound than any other quarterback in the draft and looks like a Week 1 NFL starter. But he’s not seen as a sure No. 1 overall pick, perhaps because of issues about his personality.

Quessenberry said that notion was off base, and it was ridiculous to believe Rosen’s teammates have any issues with him.

“We see him every day, we work with him every day,” Quessenberry said. “We know the type of guy he is, the type of teammate, the type of player he is. The type of grade-A human being he is.”

Quessenberry talked up Rosen’s leadership, talking about a time last season when he pulled the offense together and vocally admonished his teammates to correct some issues. Quessenberry said his message was heeded, and the Bruins averaged 32.5 points per game.

“He’s going to be a great locker room guy and people are going to ride behind him,” Quessenberry said. “He loves the game and learning about the game.”
